The Structural and Functional Impacts of Invasive Psidium cattleianum in Forests on the Island of Hawai’i

Ecosystems
Abstract During the past century, the proliferation of invasive species has contributed to loss of biodiversity and ecosystem degradation. In forests, invasive tree species can alter ecosystem function, but the underlying mechanisms of these changes are not fully understood. We use the ongoing invasion of P. cattleianum on the Island of Hawai’
